STEAM-RADIATOR.

SPECIFICATION forming part of Letters Patent No. 238,529, dated March 8,1881.

Application filed November 9, 1880.

To all-whom it may concern Be it known that I, LOUIS G. RODIER, acitizen of the United States,residing at Westfield, in the county of Hampden and State of Massachusetts, have invented new and usefulImprovements in Steam-Radiators, of which the following is aspecification.

My invention relates to the details of construction of the steam-passagethrough radiators, and to the construction of radiators consisting of aseries of independently-circulating sections or stands, the object beingto simplify said construction, and to compel a direct circulation ofsteam through the radiator from end to end and through each sectionthereof, from the entrance to the exit, in succession, and to obviatethe possibility of air-filled space in a radiator while the steam inletand outlet are open.

In the drawings forming part of this specification, Figure 1 is a sideelevation of a compound radiator consisting of a series of singleradiators or sections embodying my improve ments. Fig. 2 is a verticalsection of one of 2 5 said single radiators or sections set upon asingle base. Fig. 3 is a plan view of a portion of Fig. 1, showing twoof the single radiators thereon. Fig. at is an end view of the compoundradiator-base. Fig. 5 is a transverse 0 section through the base of thesingle radiator, Fig. 2, on the line 90 x.

D is the compound radiator-base. E are air-circulatin g openings, of aivindow form, provided with slat-like coverings. A is the steam- 3 5circulating single radiator. 0 is a diaphragm set vertically in saidsingle radiator across its base. a is a hole through diaphragm c. i i isa steam-passage through the vertical portion n of the radiator A. B Bare pipes conveying o steam either to or from the radiator. 0 is thebase of the radiator A. h is a single radiatorbase. 8 is a bolt securingstand or base h to the radiator A. m) are steam-connection openings inthe base 0 of the radiator A, one on 5 each side of the diaphragm'e. t tare steadyblocks on the sides of the single radiator A,

and g is a binding-rod passing through a web near the top of the standsor radiators A, as

placed upon base D, Fig. 1.

The essential feature of my invention con- (No model.)

sists in so constructing the single steam-circulating radiator A that itis practically a steamconducting pipe, conveying a current of steamwhich is admitted to the base 0 through one of holes 0 up through oneside of the vertical 5 5 portion a of the radiator, and down through theopposite side thereof into the base 0 on the opposite side of thediaphragm c to that where it entered, and escaping from thence by thehole a opposite to the first-named one. Thus no air can find such alodgment in this radiator, after steam is let on, as will prevent thesteam from reaching and heating every inch of its surface whichsurrounds tlie steampassages therein; and hence this radiator is moreeffective for heating purposes than any other.

The steam-circulating radiator-stand A con sists of the base 0, ofcircular form and hollow, as shown in Fig. 5, having its opposite flat7o sides perforated'with the openings '0, to which may be attached thesteam-connecting pipes B B. Transversely across base 0, and dividing itabout centrally, is set the diaphragm 0. From each side of base 0 thehollow vertical portion a of the radiator branches off, meetingcentrally at the top, and providing a conducting-pipe from one side ofbase 0 to the other.

By reference to Fig. 5 itwill be seen that the diaphragm c compels thesteam which enters one of holes '0 to enter the lower end of only one ofthe vertical portions of the single radiator A, and passing aroundthrough passage z", to be discharged through the lower end of theopposite vertical portion upon the opposite side of the partition ordiaphragm c. to that where it entered. The diaphragm c has a hole, 0,through it at its lower edge, located lower than the lowest point of thesupply and discharge openings 1) in the base 0 of the ra- 9c diator A.Said radiator A may be made of any desirable size, and, mounted upon itsbase h, may be used advantageously as a direct or indirect radiator,wherever nothing larger is needed; but when considerable heating-sur- 5face is required in one location a number of the single radiators A maybe connected to gether, as in Fig. 1, and steam be circulatedcontinuously through a group of any number, the steam being forced tofollow successively 10o from one stand to another through the whol line.

Base D is provided with suitable projections on its top, as shown, uponwhich the two end radiators thereon may rest, secured in any suitableway, as in Fi 1.

It will be observed that the radiators A are provided with steady-blockst t upon either side thereof near the top, as in Figs. 1 and 3, whichblocks interlock, as shown, when said stands are locked together in agroup, whereby the end radiators support the intermediate ones in anupright position. The radiators A are connected one to the other, as inFig. 1, in the usual manner, and a binding-rod, g, serves to hold theirupper ends firmly together. The supply and discharge pipes B B areconnected to the outer radiators of the series, and steam may beadmitted at either end.

The base D, supporting the series of stands A, is made open at the top,asinFig.3, andits sides are provided with a series of windowshapedopenings, E, provided with slat-like coverings, between which air canfreely pass into the base, and from thence escape upward through theopen top and flow up and around the grouped radiators, whereit becomesheated. The slat-like coverings across the openings E project from thesides of base D sufficiently to allow of grinding and finishing oif theedges of said slat-like coverings, so that they may be easily niekel-'ilated, if desired.

A compound radiator thus constructed from a series of said singleradiators A is, as will be seen, a continuous coil of steam-pipe,providing a sinuous passage for the steam, through every part of whichthe steam must pass and penetrate.

The water which may accumulate in the base 0 of the single radiators Acan freely pass by the diaphragm c, flowing through the hole 0 therein,and tlow off in the direction of theout passing steam and since saidhole 6 is lower than the lowest pointin the openings 21 on each side ofsaid base 0, it is obvious that the passage or holee will always besealed by water, so that no steam can pass through it.

I am aware that radiators set upon a horizontal base forming asteam-chamber which is divided by partitions to cause the steam to flowup one leg and down the other of hollow radiators secured thereto arenot new, and that it is common to construct radiators to be sethorizontally, in which a partition is set to cause the steam to flowfrom one end around to the other; but I claim neither of theabove-described constructions; but

What I claim as my invention is 1. The hollow radiator A, consisting ofa single casting adapted to be set vertically, and having within itasteam-passage, Mi, leading from its horizontal feed-pipe B upon oneside of the diaphragm 0 to the top of said radiator, and down to adischarge-o1.)ening upon the opposite side of said diaphragm,substantially as set forth.

2. In combination, the oblong base D, having two projections on its topside, as shown, and the series of three or more veriical radiators, A,secured together side to side, and having the steady-blocks t t thereon,and forming a steam-passage from one end of said series to the otherend, running from the bottom to the top, and from the top to the bottomin each radiator in succession, substantially as set forth.
